I don't believe anyone has the authority to determine the answer to this question for the entire human race. We exist here. If anyone thinks we don't deserve to be here, they can go ahead and advance their cause by offing themselves first, but don't expect me to keel over and die just because they think we're a plague or whatever.

You would have to more adequately define "Deserve" in order to get an accurate response. That said.... whether or not humans, or any animals, "Deserve" to live on Earth is a complete and total non sequitur. Humans are the product of the Earth and the evolution of life, so attempting to treat humanity and the Earth as distinct entities with no intrinsic connection simply doesn't work.

Whether we do is neither here nor there. Though we did not choose to be of Earth, it would seem that we are here to stay. If you approach this planet with hostile intent, know this: We will defend ourselves. We will defend humanity. We will defend... our home.

In a religious sense, we were given the planet to live on and therefore it doesn't matter whether we deserve to or not (we don't but God’s grace, mercy, and so forth).

In a secular sense, we took it. It’s ours. Who cares whether we deserve it or not. You can pry it from our cold dead hands if you want it (if you can kill us before we nuke it to prevent you from having it instead).

Whether we are "bad" for the planet is meaningless from either perspective.

Just because you were born some place doesn't mean you deserve it, at all. By that logic people born in opulent situations somehow deserve to have better lives while those born into hardship deserve to suffer. I resent that completely.
